I’ve tried all the various button combinations. iTunes tells me the phone has to be restored, which will obviously result in the loss of everything on the phone. I tried downloading an app (Tiny Umbrella) that looks like it was intended for the jailbreak community that says it will get it out of recovery mode without data loss. The app didn’t even launch correctly. Any ideas? It’s my son’s phone, and he’s pretty bummed.

Edit: the screen does not turn on, but iTunes sees it.
